FLASH-LIGHT DEVICE.

Specification of Letters Patent.

Patented Oct. 1c, 1917.

Application filed May 20, 1916. Serial No. 98,966.

To all whom it may concern:

Be it known that I, NATHAN E. GOLDFAD- DEN, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Flash-Light Devices, of which the following is a specification.

My invention relates to improvements in photographic flash-light devices, and has for its object the production of a device of this character which will be of simple construction, one which may be readily taken apart and confined in a small space for transportation or carriage inthe pocket if desired, and one which will be efficient in use.

Other objects will appear hereinafter.

With these objects in view, the invention consists in the combinations and arrangements of parts hereinafter described and claimed. I I The invention will be best understood by reference to the accompanying drawings forming a part'of this specification, and in which,

Figure 1 is a vertical section through a flashlight device embodying the invention, and

Fig. 2 is an end elevation of the device.

The preferred form of construction, as illustrated in the drawings, comprises a comparatively thin, wide fiat plate 1 of insulating material, fiber being preferably used. Provided centrally at the under side of member 1 is a hollow cylindrical handle 2 open at its lower end. The handle 2 is formed of insulating material. Arranged at the upper end of said handle are two spaced parallel comparatively thin, wide terminals 3 and 4, which are secured to said handle by means of rivets 3 and 4 respectively. The terminals 3 and 4 project through slits 5 and 6 which are formed in the member 1, snugly engaging therewith so as to serve to lock the parts together, through friction. The arrangement is such, however, that when desired, the member 1 may be moved upwardly from engagement with'the terminals 3 and 4, in which case the device will occupy a very small space so as to permit of ready carriage in the pocket or other place for transportation.

Mounted in the handle 2 is an ordinary dry battery or cell 7, held therein by the screw cap 8 which closes the lower end of said handle, said cap being threaded upon a ferrule 9 which is secured to said end of said handle.

The terminal 3 is formed'with a depending tongue 10 which projects through the upper end of the handle 2 for engagement with the upper pole 11 of the battery 7. A helical compression spring 12, arranged in the lower end of the handle, engages with the lower end of said battery topress the same upwardly in order to normally hold the pole 11 in contact with the projection 10 of terminal 3. The opposite pole of the battery 7 isengaged by the spring 12 which serves as an-e'lectrical conductor for conducting the current from. said pole to the cap 8. The latter, in turn, is adapted to conduct the current to the ferrule 9, said ferrule being connected with the lower end of a strip 13 of conducting material provided at the inner side of handle 2 which extends upwardly and connects with one side of a manually operable switch 14 of approved design which is mounted upon the outer side of the handle. The opposite side of said switch'is connected by a conductor bar 15 with the terminal 4. By this arrangement then, it will be seen, that a circuit is completed between the terminals 3 and 4, through the battery, which circuit may be opened or closed by simply shifting the movable control member 14 of the switch 14.

Cooperating with the upper ends of terminals 3 and 4 is a fuse wire 16. Said fuse wire is wrapped upon a spool 17 which is loosely mounted in a bracket 18 secured to the under side of member 1. The fuse wire is passed from said spool upwardly through an opening 19 in the member 1, being thence engaged with tapering slots 20 which are formed for the reception thereof in the upper ends of terminals 3 and 4. When thus engaged with the terminals 8 and 4, it will be seen, that said fuse wire will serve to electrically connect said terminals, and so that, upon closing of the switch 14, the current flowing through said fuse wire will heat the latter to incandescence. In use, the flash powder is placed centrallyupon the support 1 around the terminals 3 and 4, so that, upon the heating of the fuse wire to uponthe support, will flow outwardly, leav-v ing only a sort of hill between said terminals, the central portionor peak of-which will engage With the fuse Wire.

v EVVhen-theflash takes place, the fuse Wire between theiterminals is generally melted or fused. NVhen this occurs, it isonlyvnece's- Sary to unwind vazfresh port on of sald fuse wire and engage the same with the'ter ninal' slotsi20, vThe bracket 18, which supports. the spool 17, is-formed with a depending fiange 22 which serves as a shield to pre: ventinjury to the fuse wifi-eupon said spool by anyzfiash passing through theppening 19,- when the explosion takes place.

ilVhile I have illustrated and described the preferred form of construction for carrying my invention ,intoell'ect this is capable of variation and modification .with out departing'from the spirit ofthe inven-.

. tion. I, therefore, donot wish to-ybe lim-,

ited to the precise details ofconstruction set forth rbut desire to avail myself; ofsuch variations and modifications as come Within the scope ofthe appended. claims.

Having described my invention what I Copies of; ti i s jpatent may be obtained f or.

claim as new and desire to secure by Letters battery mounted in said-handle; a pair of compartively thin, wide spaced parallel terminals interposed in the circuit of said battery-and projecting upwardly from the upper end of said handle through said supoort; a fuse fiYlIG'ildLPtQd to connect said terminals; tapering slots in the upper ends of said terminals-for thereceptionof said fuse wire, there being: openings in said; terminals below said slots; and a switch for controlling ,said circuit, substantially as do scribed.

Aflash-light device comprising a sup-1 port for flash powder anelectric battery a pair of spaced terminals interposed'in the circuit of saidbattery and arising 'from said support; and a "ZfUSQ WVlIQ adapted to vcon nect said terminals, there being openings in said terminals below said points'of, engage Inent therewith of. said fuse Wire, substantially as described,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
